Alba was chosen for the magazine's Summer Must List issue because she's about to return to the big screen to reprise her 2005 "Sin City" role as stripper Nancy Callahan in Frank Miller's "Sin City: A Dame To Kill For," set to hit theaters in August.

"I'm kind of a prude, and I didn't really understand. They would always ask me provocative questions about my sexuality, my this or that," the actress told Entertainment Weekly of earlier in her career.

I mean, I didn't even know how to walk in heels until I went to the Golden Globes for the first time."
